Members of Maine’s congressional delegation universally condemned comments President Donald Trump made on social media in which he suggested a group of Democratic lawmakers exhibited “seditious behavior, punishable by death.”

Trump referred to a video shared this week by six lawmakers, all of whom served in military or intelligence roles, that urged members of the military not to follow any illegal orders. The lawmakers did not indicate their message was in response to a specific incident or scenario, though some of the lawmakers have raised concerns about Trump administration military actions.

Sen. Elissa Slotkin of Michigan, told the New York Times, for example, that she had heard from active-duty troops who were concerned about the legality of strikes that have targeted people accused by the administration of trafficking narcotics by sea. The Trump administration has carried out nearly two dozen such strikes this year.

“This is really bad, and Dangerous to our Country,” Trump wrote in a post on his social media platform Truth Social in response to the video. “Their words cannot be allowed to stand. SEDITIOUS BEHAVIOR FROM TRAITORS!!! LOCK THEM UP???”

“SEDITIOUS BEHAVIOR, punishable by DEATH!” he wrote in a follow-up post.

“HANG THEM GEORGE WASHINGTON WOULD !!” said yet another post.

Trump said in an interview Friday on Fox News Radio that he wasn’t intending to actually threaten the lawmakers with death, but said “they’re in serious trouble.”

Members of Maine’s congressional delegation, meanwhile, condemned the president’s reaction.

“The president should not be calling for the death of members of Congress because of what they say, regardless of how strongly he disagrees with their comments,” Sen. Susan Collins, a Republican, said in a written statement. “Such incendiary comments risk sparking political violence.”

Sen. Angus King, an independent, called the response “shocking” and said it illustrates Trump’s “depth of his contempt for the law and our constitution.”

“All these people said was common knowledge: military officers are not required to follow illegal orders,” King said in a written statement Friday. “That is a simply a statement of fact just like the sun rises in the east, and for the president to somehow characterize that is a traitorous or some other heinous crime, which could take the death penalty, is an insult to the American people and shows his lack of respect for the Constitution and the rights of our people.”

Rep. Chellie Pingree, a Democrat representing Maine’s 1st District, said in social media posts that the lawmakers are “rightfully alarmed” by some of the administration’s directives.

“The president of the United States believes he should be able to execute members of Congress,” Pingree wrote. “Their supposed crime: putting out a video advising the intelligence community and military personnel not to follow unlawful orders.

“This is totally disgusting — and downright terrifying.”

Rep. Jared Golden, a Democrat from Maine’s 2nd District and former U.S. Marine, said in a written statement Friday that “it is a fact, and one drilled into members of the Armed Services repeatedly, that we have a duty to disobey orders we know to be illegal or unconstitutional.”

“This is a basic tenet of military discipline, and for good reason,” Golden said. “It’s wrong to politicize our military, just as it’s wrong to inject threats of political violence into our politics.”
